Archived seismograph traces (updated all the time; any missing days means there was no graph that day):(The percentage is the "activity percentage," which is a number I made up myself
as an attempt to guess how much trace activity there is in a graph from its file size. Note that
all of this is entirely guesswork on my part, albeit educated guesswork... I just had to have
some way to tell how "busy" a graph is without having to actually look at it. Bear in mind,
a high activity doesn't mean "quakes"; a lot of it is just wind and other noise, like this garbage
(which gets a 0.0% activity rating). But a lot isn't noise. Just... don't trust these numbers.
They have no basis in scientific fact.)
